Dx for penicillin testing

If we are testing a patient for a penicillin allergy due to a patient's reaction to penicillin which occurred months or years prior to the test, is it more appropriate to report a history of penicillin allergy code (V14.0), or an adverse effect code of 995.27 with E930.0?

I see where the index refers you to 995.27 for drug allergy, but I'm not certain you'd use it in this situation - I would think that poisoning codes are more appropriate for acute episodes, when the patient is experiencing an allergic reaction, but I could be wrong about that. Hope that helps!
